4 X 100

That is 4 studs centred on a circle 100 millimeters in diameter.
The same as lots of Hondas, Nissans, Subarus, and Mitzis - but front wheel drive wheels have more 'offset' and need spacers to move them out ot fit in the proper position.

The stock GT tire was 165/SR-13 (about a 75 series tire). A very common fitment is a 185/70R-13 (virtually no speedo error). Bigger tires and rims are often used (such as a 205/60R-13 or even a 205/50R-15); the usual advice is to adjust the aspect ratio to make the outside diameter the same, so as to avoid speedo error and such. Wider tires might handle better, but there are trade-offs in ride, interference and mileage. MUCH more discussion is available within this Forum, where I moved this thread.

It would seem that we have a couple of new members asking the same question tonight. I have moved this thread to the correct Forum (Wheels and Tires). If you could be so kind, please use the search function, or at least look through the Forums by heading to see if you can find the answer to your question before you start a new thread. And if you start a new thread, please try to start it in a Forum that suits the question. And as a rule, it is ALWAYS better to add to an existing thread than to start a new one.

By the way, Opel is a "proper" name and is capitalized. Correct spelling is appreciated and is made quite easy by the spell check feature (the little check mark with the "ABC" under it next to the posting box)

I found that 13 inch Goodyear Eagle slicks work really awesome especially if the ones on the right side are lots bigger than the ones on the left. They only rub when we get too close to a Mustang, then all hell breaks loose, they (traffic behind us) tell me. IDK, I just keep going. Let them (traffic behind us) deal with it.
Pretty work, Keith. Knew that was coming...

165sr-80 X 13

Opel GTs had tiny wheels and tyres from the factory - radial tyres were quite 'new' back in 1969-73 and the small radial tyres gave much better grip than the conventional cross-ply tyres used up till that time. They also give a very good smooth ride because the tall rubber sidewalls flexed and acted as part of the suspension.

There are huge debates on be found on this site (with the Search function) about replacement modern 14/15/16/17/18 inch tyre sizes and wheels !!

Thanks for alot of the info I have found here on this site its very appreciated. its a tremendous help. Since being new to the whole Opel world and Female trying to work on a car at that. I do image so that I and cars don't get along but none the less, I do know how to fix them by the time I've had them for a month. Which I do believe is a good thing. Any who any one know where to find some really neat looking rims for an Opel like mine. These snowflake rims i have, have just got to go. They don't match at all.

Most 4x100 rims will fit, but depending on the offset, you will probably need spacers. People are either with them or against them. IMO, as long as you aren't doing any dangerous driving, like super tight corners, you should be fine. With a larger diameter, remember you will have to go with a lower profile tire or like in your case, rubbing will occur.
